该研究在叶尼塞样带（65°46′n, 89°25′e）的图鲁汉斯克研究站进行。落叶松（Larix gmelinii）鲁柏（Rupr.）是优势的上层乔木。本研究在森林类型绿苔和地衣类群火灾后的同龄成熟（110年树龄）和过成熟（380年树龄）落叶松林中进行了4个永久性试验。碳循环参数基于生物识别方法进行评估。碳库和通量的定量分析表明，北针叶林的生态系统净生产量平均为净初级生产量的32%。成熟和过成熟青苔落叶松林的大气co2汇为1.22和0.74 t C ha−1 - 1，地衣类型的大气co2汇为0.65和0.35 t C ha−1 - 1。树木层的净碳汇占净初级生产碳的9%，地面植被占15%，植物残体积累占光合作用吸收大气碳的8%。
The study was carried out in the Turukhansk Research Station of Yenisei Transect (65°46′N, 89°25′E). Larch (Larix gmelinii (Rupr.) Rupr.) is the dominant overstory tree species. The research has been conducted on four permanent test plots in same-age mature (110-year old) and overmature (380-year old) post-fire larch stands of green moss and lichen groups of forest type. Carbon cycle parameters were assessed based on a biometric method. Quantitative analysis of carbon pools and fluxes shows that net ecosystem production of north taiga larch stands averages 32% of net primary production. Sink of atmospheric CO2makes 1.22 and 0.74 t C ha− 1year− 1for mature and overmature green moss larch stands, and 0.65 and 0.35 t C ha− 1year− 1for lichen type. Net carbon sink in the tree layer make up 9% of net primary production carbon, ground vegetation – 15%, and dead plant residues accumulation – 8% of atmospheric carbon uptake via photosynthesis.
